hop of those help? I am very new to python and also to scrapy. I want to scrape the data from wikipedia but things didn't work out. Everytime I do scrapy crawl wiki, I always get; "TypeError: 'WikipediaItem' object does not support item assignment". How do i fix this and for me to scrape successfully the details from wikipedia. , You named your scraper the same as the WikipediaItem you imported:
code :
from wikipedia.items import WikipediaItem

class WikipediaItem(BaseSpider):
    # ...
class WikipediaSpider(BaseSpider):
    # ...

help you fix your problem idx is just an integer like 0 and there is no such thing a 0[0]
you want to use val which is your item from your list.
code :
for row in game_board:
    for item in row:
        item[0] = 0
        item[1] = 0

it helps some times I have two matrices , Your problem is right here:
code :
Xij[i,j] = ai[i] * Nij[i,j]
>>> def test(): print "Hi"
...
>>> test[1] = "yo!"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'function' object does not support item assignment

"TypeError: 'unicode' object does not support item assignment" in dictionaries

will help you I am trying to build/update a dictionary. I have nicknames as keys in temp_dict and looking for ids to add. , Most likely you have put unicode string in temp_dict somewhere:
code :
>>> temp_dict = u''
>>> dic2 = {u'nickname': u'45sss', u'account_id': 553472}
>>> x = dic2['nickname']
>>> y = dic2['account_id']
>>> temp_dict[x] = y
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'unicode' object does not support item assignment
>>> temp_dict = {}
>>> temp_dict[x] = y
>>> temp_dict
{u'45sss': 553472}

I'm seeing "TypeError: 'tuple' object does not support item assignment" on spyder

fixed the issue. Will look into that further The issue is with your np.linspace statement. Here is doc for linspace. The syntax is: numpy.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None, axis=0). So you only need to give the starting and ending points, and the number of intervals you would like. So after changing your program to this:
code :
import numpy as np
import matplotlib.pyplot as plt

def dydt(t,y):
    dfdt = y / ((t + 1) ** 2)
    return dfdt

def IVPsolver2(dydt_fun, y0, t0, t1, t2, tf, h):
    n = 50 #points
    h = (tf-t0)/(n-1) #step size
    t = np.linspace(t0,tf,n) # <----- see change here ---- 
    y = np.zeros(n) #preallocate zeros
    yp = np.zeros(n)
    m = np.zeros(n)
    mc = np.zeros(n)
    yp[0] = y0 #first yp at y0
    y[0] = y0 #y is 0
    t[0] = 0 #t is 0
    for i in range(0,n-1):
        m[i] = dydt_fun(t[i-1],y[i-1]) #calculating slope
        yp[i] = y[i] + m[i]*h #calculating predicted y at slope y
        mc[i] = dydt_fun(t[i+1],yp[i]) #slope corrector, 2 step
        t[i+1] = t[i] + h #t going by stepsize
        y[i+1] = y[i] + ((m[i]+mc[i])/2)*h #corrected y
    return t, y

def main(): #plotting  
    x2, y2 = IVPsolver2(dydt, 1, 0, 0.2, 0.4, 0.6, 0.2)
    plt.plot(x2,y2, 'o', mfc = 'purple')
    plt.show()
    return
main()
